Here's a simple 2-line recipe which monitors an item, and plays the value. It only plays when the value changes, cutting down on chatter.
The code consists of one logical switch and one special function.
Logical switch L1 detects a change in value of an item
Special function SF1 plays the value
[5 May 2016] OpenTx will ignore the SF if the source is not referenced elsewhere. If you can't get any voice, make sure that the item being monitored is referenced in a channel or input.
To Scott Page for the original concept of a 'talking knob' on RC Groups. The recipe presented here is a much simplified version.
